MULTIPLE CHOICE Question 11 What does Le Châtelier's principle state? A Equilibrium cannot be re-established once it is disturbed. B A system at equilibrium will remain at equilibrium forever. A system will react to re-establish equilibrium if it is disturbed. A reaction will proceed to completion if equilibrium is disturbed.
(#30) The Equilibrium Constant and the "ICE Chart" Phosphorus pentachloride gas is formed according to the reaction by adding chlorine gas to phosphorus trichloride gas. Then the reaction reaches equilibrium. The equilibrium constant, Kc, equals 49.0 at 230°C. If 0.500 mole each of the reactants are added to a 5-L container, what is the equilibrium composition at 230°C? (30a) In blank #1, type-in our answer for the concentration of phosphorus pentachloride in the product at equilibrium. The unit is Molarity, but enter only the value of your answer with two decimal places. (30b) In blank #2, type in your answer for the concentration of phosphorus trichloride at equilibrium with two decimal places. (30c) In blank #3, type in your answer for the concentration of chlorine gas at equilibrium with two decimal places.
Give typed explanation
Question 20 Which statement best describes general equilibrium? Equilibrium is reached when the reaction stops. There is only one set of equilibrium concentrations that equals the Kc value. At equilibrium, the rate of the forward reaction is the same as the rate of the reverse reaction. At equilibrium, the total concentration of products equals the total concentration of reactants.
